I've spent long hours to find this file, but I don't deserve all the credits, respect the author!! (who recompiles the file)Apparently the Win7 SP1 affects a Python function, which is located in the "multiarray.pyd" file of Frets.This solution is working on MFH 3.030 but should work great on Alarian, RFMod, etc...You just have to replace the "multiarray.pyd" file in your "..\FretsOnFire\Data" with the one in this archive:

Launch FretsOnFire.exe and, let's rock!

PS: If you experience problems, just know that during my researches, I installed Python 2.4 and 2.6, and the unofficial Numeric python library (http://www.megaupload.com/?d=FCDMWIDV).so if you still have errors, try to install them too! (but should work without 'em)

Get me some division,called the dead by night,to the god allay the chaos!Chains to my last victim!Set up the lights on the way to the skies,Raising my sword to the lord!calling your death a black obsession,the only way OUT!RIGHT!

So wait salvation,Come unto me!Life to the saint,Life for me!Your,Your lord,Smashed this bloody god on earth,its always by my side,take me to the place to die for you,and give me life in flames!

It's black after light, Odyssey say i'll be dead,A lord of chaos to be,Searching my dreams of the lives in my vision,night of war, yeah!YAAAAAWWWW!!!

Son of the night was left to destroy.wait now to destroy...Yow!

[SOLO]

Say,why this bloody god on earth,is always by my side,Take me to the place we die for you.

HEY!

YAAAAAWWWW!!!

The last song of hate,song to my heart,tonight's gonna be,something wild!
